Thumb shifters question?! Hi, I am wanting to change the down shifters on my Trek 1420 road bike to thumb shifters, will the Shimano A050 setup work?

Yes, they sure will. A far better set up, IMHO, than downtube shifters. These won't take your hands off the bars to make shifts. In fact just a quick thumb movement it all it takes, just twist your wrist up or down to activate. Also better than the old 'stem shifters'. Not quite as good as Integrated Brake Lever shifters - but far less expensive, 25 versus 120 dollars.

No I believe you can't. You need to use shifters with the same gear ratio that your bike is configured with in order for them to work properly

The main thing is, SRAM REAR derailleurs will only work with SRAM REAR shifters, and vice versa. You can never use SRAM with Shimano in the back. It doesn't matter in the front.

it works OK. in my situation, I'm probably better off getting the twist style shifter. I have a Specialized HR.

You can use the newer version provided the gearing is the same. I used this Sora to replace a Shimano shifter from the 90s so I am sure it would be fine to upgrade an older version of Sora (again, provided you are using the same number of cogs on you front crank and rear cassette).

Sorry, but I only have experience with Adams Trail a Bikes and the connection system they use. Have you checked the Trek site or check with a dealer if one is close by. Sorry not more help,

NO! No, it will not work. The SRAM shifters only work with SRAM rear derailieurs, because the ratio is 1:1 vs Shimano 2:1. The front derailieurs for both systems are interchangeable as they use the same ratio.

Well, they are two different companys. I think you're taking a chance, but if Shimano doesn't make a similer product, it might be a chance worth taking. Otherwise, buy and use a chain link designed for a Shimano chain. Good luck

bb-ty30 is interchangeable with bb-un55 acording to shimano info i found on web

Not 100% sure of my answer but since there is only one cable involved can't believe it would not work. That said I have over 4000 miles with the shifters and they work perfectly.

I can't say for sure about your shifters, but I mounted some old 7spd Deore shifters on these bars with no problem. Also some mountain brake levers which were fairly standard, so you'll probably be able to mount your shifters fine. I measured the bar's diameter, and it looks close to 22.2 mm. Hope that helps!

This is a 10 speed derailleur and will only work with that kind of setup. In order to use it you will have to update your shifters, cassette and even your front derailleur.

I use it on a Bianchi road bike combined with a Shimano 6 speed freewheel. I have a friction shifter and it works very well.

NO! Absolutely not! This is a SRAM 1:1 pull ratio shifter that works with SRAM 1:1 ratio rear derailleurs NOT SHIMANO!!!!! It will work with a SRAM rear derailleur & a shimano cassette but NOT THE OTHER WAY AROUND. Period.

I have this on my Trek 7.2 fx works fine I have the 48/36/26 since I'm mostly ride on flats not a lot of uphills n I don't carry any load on the bike. The 42/32/22 is good if u carry a lot of load on the bike. Hope this helps.

yes it will work. Adjusting for perfect shifting was a little challenging. It is best to use Sram rear derailer and cassette with Sram shifters and vs.

Yes. It works with all 21 speed bikes. I would check the derailleur first and make sure that your screws aren't out of adjustment. There are good videos on YouTube telling you how to do that. If that doesn't fix it, the grip shifters are a good choice.
